After uploading my last program to my Go it failed to attach to the debugger and disappeared as a usb device on my computer. Now when I plug it in it shows up briefly while all the leds are on then once the turn off and just the power light is on it disconnects and disappears as a usb device. Is there a way to clear the program off the Go so it's a nice clean slate to put a new one on.
I have tried plugging it in as VS starts deploying but it always disconnects before it can reboot it and send over the files.
Netduino Go disappears from USB port at startup

Hi BlackLamb,
Did you use the UsbClient feature of your Netduino Go by any chance? Or open up one of the USB pins as a Port in your code?
There is a full erase-and-reflash procedure for Netduino Go. Do you have a moment to drop into Netduino Chat (Chat tab at the top of the page)? We can also write it up on the Wiki.
For reflashing for now, you'll want to grab a copy of the following program:

No I did not try using the USBClient feature that I know of. I was trying to get my VoiceShield driver I had ported to the Netduino working with the Go and the shield base. You can look at my code here http://voiceshieldcs.codeplex.com/ if you want to try to repo this.
Thanks for the fast reply.

Hi BlackLamb ,
I've downloaded the latest source of the project (voiceshieldcs_99c7a951ecdd) but I see you're still using Secretlabs.NETMF.Hardware.Netduino.
That pin mapping may conflict with Netduino Go!.

Thank you for pointing that out. I made it a little further now IE it now does not lockup the board
but now I'm getting this at start up as soon as I try to make any OutputPort on the ShieldBase.A first chance exception of type 'System.Exception' occurred in NetduinoGo.ShieldBase.dll
An unhandled exception of type 'System.Exception' occurred in NetduinoGo.ShieldBase.dll
Uncaught exception

And a few minutes after posting this I figured it out I needed to create my ShieldBase and hookup my ports in Main.
